Here is how I find Prokon stuff! I search "1234567890" (TEXT) or "31   32   33   34   35   36   37   38   39" (HEX) If you scroll down after the FF's and see the 00's, and 01's these are the Prokon/Euro bits. If you don't see them F3 (Ols) or continue to search until you do!. There are usually more than 1 instances of "1234567890" or "31     32   33   34   35   36   37   
38   39", Also the order is usually the same see Prokon---Text image. I found it works on most files.

Aaand now you have to define it

Yes. I guess that I will have to test the different items to see if they are what I think they are. I have noticed that the car schematics list things differently than the ECU schematics.
